This invention relates to a device for providlng efcient and usefulmeans for splicing a new web roll to a running web coming from an eX-piring roll.

The principal objects of the invention are to provide a new combinationof a torque motor driven type of tension device,;which, in itself, isold, with means acting between or around the tension membersto-pressvthe web against the rotating fresh roll; to provideelectro-magnetic means for actuating or operating the web pressing meansin combination with electro-magnetic means for operating web severingmeans, acting between or around the tension members; to provide ayielding web tension means actuated to change the tension by mechanicalmeans at the other end thereof in order to prevent the running roll fromoverrunning and flooding the device withrpaper, and to combine the samewith the other features above mentioned;

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to drawing, in which Fig. l is an end view of aweb splicing device constructed in accordance with this invention,showing the web pressing means just going into the accompanying actionto press the web against the fresh rollY in full lines and showing itretracted in dotted lines, and

Fig. 2 is an elevation of the bottom of the tension device.

A conventional type of reel 3 is shown for supporting the running rollor exhausting stub A and fresh roll B. This reel is shown as supportedon a main shaft I carried by a base or pedestals 2 and the reelcomprises two spiders between which are mounted the web rolls.

To provide means for rotating the fresh roll B up to web speed a shaft Iis shown which may be driven from any convenient source of power, suchas the printing press itself. Bevel gears and 6 operate a vertical shaft"i, which in turn operates other bevel gears 8 and 9, and a pinion Il)and gear I I. The gear I I is rotatably mounted on the shaft I and hassecured to it a large gear I2. The gear I2 meshes with gears I3, one foreach of the rolls or spindles. It may be stated that an appropriateclutch may be used for engaging the spindle of the Vfresh roll and itsgear I3 to transmit rotation from the gear I2 to the active spindle torotate the fresh roll prior to and during splicing. No attempt has beenmade to show such a clutch and any type of clutch can be used.

On brackets I4 carried by a brace I5, which constitutes a part of theframe of the printing press, is mounted a shaft I6 free to turn in thesebrackets.V On this shaft is carried oscillatably a brush frame Il. Thisbrush frame is adapted to be raised and lowered by swinging it and itsshaft I 6 by suitablefmeans, either manually operated or motor operated,as desired.

Y.Tension straps I8 are shown as being yieldingly secured at theirbottom ends by meansof springs 43. These tension straps are carried overindividual eccentric pulleys 4I at their upper ends. These pulleys 4Iare secured to a shaft I9 which is rotatably mounted in the brackets I4.

A sprocket 20 is carried by this shaft I9, which is operated by a motor23 through a sprocket 22 thereon and a chain 2l. This motor is operatedin a direction to serve to keep the'tension and prevent the running rollA from overrunning and thereby flooding the paper.

On the frame II is carried a shaft 23 capable of turning. Fixed to thisshaft are a series of arms 25, each pair of arms carrying a brush 24 sothat all these brushes will move together when the shaft is oscillated.These brushes project through spaces between the tension straps I8 sothat they can contact with the web W.

For the purpose of accomplishing this there is a solenoid 21 adapted tolift a pivoted latch 28 and release a toe 29 fixed on the shaft 26. Whenthis toe is released, springs 33, acting through stop collars 3l, rods32 and arms 33 secured to the shaft 26, oscillate said shaft and therebymove the brushes forward toward the web and press the web against thefresh roll B.

A solenoid 3d is provided which, when energized, acts through a link 35and latch 36 to release a toe 31 which is secured to a shaft 38.Securely mounted on this shaft, which is rotatably carried in the brusharm I'I are a series of severing knives 39. A coiled spring then rotatesthis shaft to project the knives 39 between the'tension straps to severthe web.

After this operation the brush arm II is raised in any desired manner toinoperative position and the fresh roll B then becomes the running rolland is moved by the rotation of the reel into contact with the tensionmembers I8.

It will be seen that this device combines electromagnetic means foroperating the web pressing means with electro-magnetic means foroperating the web severing means and also combines the torque motor typetension controlling device with means for pressing the web against therotating fresh web roll to make the paster, and combines the websevering means with the same. In this way eicient and useful mechanismis provided for the splicing of a new web roll to a running web comingfrom an expiring roll.

The operation has really been stated in describing the mechanism.

Although I have illustrated and described only one form of theinvention, I am aware of the fact that mcdications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore, I do not wish to belimited in this respect, otherwise than as set forth in the claims, butwhat I do claim isz- 1. In a web splicing device, the combination with areel adapted to carry a running roll and a fresh roll, of a frameadapted to be moved from operative to inoperative position, aweb-pressing means movably mounted on the frame, a solenoid, aspring-pressed plunger normally held in inoperative position, and meansactuated by the solenoid for releasing saidv plunger, said lastnamedmeans constituting a latch connected with the Web-pressing means, saidweb-pressing means being connected with the plunger, whereby when thesaid solenoid is energized, the webpressing means will be released andthe plunger moved in a certain direction to actuate the webpressingmeans toward the web and the fresh roll, a second solenoid, a websevering means oscillatably mounted and spring actuated, means forholding the severing means in inoperative p0- sition, and means operatedby the second solenoid for releasing the severing means.

2. In a web vsplicing device, the combination with a reel adapted tocarry a running roll and a fresh roll, of a frame adapted to be movedfrom operative to inoperative position, a web-pressing means movablymounted on the frame, a solenoid, means whereby when the said solenoidis energized, the web-pressing means will be released and moved in adirection toward the web and the fresh roll, a second solenoid, aweb-severing means oscillatably mounted and spring actuated, means forholding the severing means in inoperative position, and means operatedby the second solenoid for releasing the severing means.

3. In a web splicing device, the combination of a torque motor type oftension having tension members engaging the surface of the roll,webpressing means acting between said tension members against thesurface of the roll, and means for rotating the fresh roll by powerapplied to the central axis thereof.
